    A lady had about 6 inches of soil over top of a concreate slab. The grass dies every year she said. she's added about 2 inches of scotts lawn soil to it and seeded it last year and the same thing happened... I though 4 inces of top soil she should be fine, but not in this case. I need some suggestions.

    the limestone in the concrete could be leaching out into the soil.

    one time i had this lawn, it kept dying every year, it was driving me nuts, i checked down to about 4-5 inches, everything looked fine. then i had it, and just started digging, about 8-10 inches down i found what once was an old driveway, rocks, broken up concrete, that was my problem. i don't know if theres anything that can be done other than ripping out the concrete

    This the same problem we have had on a few of our lawns with shallow sewer lines and large drainage pipes. The problem kept happening every year when it got hot and dry. Try encouraging them to put(or let you to) in a small irrigation system and a timmer so it waters during the coolest hours of the day.

    Try conducting a cheap Ph test and try boosting it or lowering it according to what it needs.

    The concrete is acting as a big heat sink. Basically you are cooking the grass.
  9. here's a novel idea trim it off the concrete!

    Does the soil stay wet?I'd think that concrete would create a barrier and not allow proper drainage.Maybe you could drill holes through the soil and all the way through the concrete to allow for better drainage.
